Minecraft Survival Mode Building Ideas?

I play Minecraft PS3 Edition and I'm on survival mode, I have a pretty nice sized house with a basement and I've made a lighthouse and an igloo. I was wondering if anyone could give me some ideas? Nothing too hard because I'm still learning. I would like to have more structures and not traps or anything like that. I've looked up some ideas, but nothing is really catching my eye so any help would be greatly appreciated!
Also, it would be nice if there was step-by-step photos and some details on how to build the structure.

I have it on the Computer I have built a castle for my house made out of quarts and nether rack, it took along time but it was so worth it bragging to my boyfriend that I have a Cooler house, there are people on YouTube that do this stuff for a living and it seems pretty cool you could steal some of their ideas and add your own spin to it
